Description
Technical field
The utility model relates to elevator and declutches technical field, particularly to a kind of elevator brake-releasing gear.
Background technology
At present, machine-roomless lift development is very swift and violent, with the application of machine-roomless lift further genralrlization, and inorganic on market
Machine room-free elevator product demand also increases day by day, but the particularity that the oppressive rescue of machine-roomless lift brings because of its design feature becomes one
Individual very important problem, existing machine-roomless elevator mainframe is arranged in hoistway, and people cannot be straight as having machine room elevator
Connect and host service function is declutched, need to operate brake-releasing gear outside hoistway.Current roomless elevator brake releasing mode has
Two kinds: one is to operate electric switch outside hoistway to declutch by electrical means, and another kind is to pass through mechanical means outside hoistway
The brake-releasing gear that operation is arranged on main frame declutches.Both modes cut both ways, and electrically implementation is simple, but
Easily be out of order poor reliability；Although mechanical type reliability is high, but the lever arm of existing mechanical, hand-driven brake-releasing gear is longer, knot
Structure is complicated, and cost is high, and big to requirements of installation space.
Utility model content
The purpose of this utility model is to provide a kind of elevator brake-releasing gear, it can be avoided that because of asking that electric fault lost efficacy
Topic, safe and reliable, and it is little to take up room.
For realizing the purpose of this utility model, adopt the technical scheme that:
A kind of elevator brake-releasing gear, including at least one brake and with brake brake-loosing mechanism one to one, declutch
Mechanism includes connecting rod, the block piece being located at the connecting rod other end that tricing line, one end be connected with brake, is coated on connecting rod and is positioned at
The first platen between brake and block piece and the second platen, at least one rolling clamping between the first platen and the second platen
Moving part, the first platen is provided with and rolling member holding tank one to one, and rolling member part is positioned at holding tank, and the second platen is provided with
The chute being oppositely arranged with holding tank, chute is circumferentially arranged and its degree of depth is circumferentially gradually become shallower as to other side by side,
One end of tricing line is connected with the second platen.
When elevator is properly functioning, the side that rolling member stretches out holding tank is positioned at the big side of the chute degree of depth；When elevator occurs
When fault needs to declutch main frame, by pulling tricing line, making tricing line drive the second platen to rotate, rolling member is gradually slided
Entering the little side of the chute degree of depth, making the second platen gradually to block piece one side shifting, the second platen moves to when offseting with block piece, and
Two disks are rotated further under the drive of tricing line, and block piece drivening rod moves, and carry brake and elevator main disengaging, real
Now declutch and rescue.This elevator brake-releasing gear uses the mode that mechanical, hand-driven declutches, it is to avoid the problem losing efficacy because of electric fault, peace
Complete reliable, and simple in construction, the first platen and the second platen pass through connecting rod and block piece pressure on the brake, take up room little, fall
Low production cost.
Below technical scheme is further illustrated:
Further, elevator brake-releasing gear also includes the follow block being fixed on brake, and follow block is provided with joins with tricing line
The through hole closing, one end of tricing line passes through through hole and the second platen connects, and tricing line is cased with back-moving spring outward, back-moving spring
Two ends offset with follow block and the second platen respectively.During declutching, back-moving spring is gradually compressed；After completing when declutching, logical
Crossing back-moving spring to realize resetting, rolling member slides back to the big position of the chute degree of depth again, makes the second platen be maintained at normal condition, makes
More convenient operation.
Further, the periphery of the second platen is convexly equipped with the connecting portion being oppositely arranged with follow block, connecting portion and tricing line
Connect and offset with back-moving spring.
Further, rolling member is cone roller, and the cross section of holding tank is half cone-shaped.Make the first platen and
Contact area between two platens is bigger, reduces stress, reduces material requirements, reduces production cost further.
Further, rolling member has four, and four rolling members are uniformly distributed circumferentially in the first platen and the second platen
Between.During declutching, the stress of the second platen is made more to balance, mobile more stable.
Further, the first platen is provided with the first fixing hole, brake be provided with first fixing hole coordinate second fix
Hole, is connected with securing member between the first fixing hole and the second fixing hole.By the first fixing hole, the second fixing hole and securing member
Coordinate, the first platen is fixed on the brake, it is simple to installing/dismounting and regular maintenance.
Further, elevator brake-releasing gear also includes the thrust bearing being coated on connecting rod, and thrust bearing is positioned at block piece
With second between platen.
Further, connecting rod is bolt, and block piece is nut.It is easily installed dismounting and regular maintenance.
Further, brake has two, and two brakes are symmetricly set in elevator main.Make brake force more stable.
Compared with prior art, the utility model has the advantages that
The utility model is when elevator is properly functioning, and the side that rolling member stretches out holding tank is positioned at big one of the chute degree of depth
Side；When elevator break down need to declutch main frame when, by pulling tricing line, make tricing line drive the second platen to turn
Dynamic, rolling member gradually slips into the little side of the chute degree of depth, makes the second platen gradually extremely offset with block piece to block piece one side shifting, the
Two disks are rotated further under the drive of tricing line, and block piece drivening rod moves, and carry brake and elevator main disengaging, real
Now declutch and rescue.This elevator brake-releasing gear uses the mode that mechanical, hand-driven declutches, it is to avoid the problem losing efficacy because of electric fault, peace
Complete reliable, and simple in construction, take up room little, reduce production cost.
